Sweden has countless castles (or 'slott' in Swedish) from its storied history. Seeing all of them would take ages. I have compiled a list of some of my favorite castles from across Sweden including Uppsala Castle, Kalmar Castle, Kärnan, Borgholms Castle, Gripsholm Castle, Vaxholm Fortress, Örebro Castle, Skokloster Castle, and Carlstens Fästning.

The island of Marstrand sits about an hour north of Gothenburg on the west coast of Sweden. The archipelago of Gothenburg is a sight to see but if you're feeling more ambitious, find your way to Marstrand where you can hike around the whole island, enjoy swedish dishes like skagenröra and kardemummabulle, while taking in views of Carlstens Fästning and Strandverket.

The Slovenian capital of Ljubljana is small with a population of just above a quarter million. But the city boasts a plethora of sights which include Ljubljana Castle and Cathedral, Triple Bridge, Metelkova Art Center, Republic and Congress Square, Cerkev Marijinega Oznanjenja, and Saints Cyril and Methodius Church, as well as plentiful green spaces like Tivoli Park!

Just a short train ride away from Lisbon, the city of Sintra is a must see. It's best known as the site for the National Palace of Pena, the colorful Romanticist Castle and one of the Portugal’s Seven Wonders. Other places to see in Sintra include Castelo dos Mouros (Castle of the Moors) and Quinta da Regaleira (a lavish garden estate and UNESCO World Heritage Site).

Uppsala is just 40 minutes north of Stockholm by train. It's the fourth largest city in Sweden (with a paltry 200k for population). Make no mistake, this charming city has great importance in Sweden as a whole. While here, you can enjoy Uppsala Castle and Linnaeum nearby. The best place in the city to experience the sunset and Uppsala Cathedral is right along the canal at Gotlandsparken.

Known for it's cheap beer and destination for stag and hen do's, there is much more to this Central European capital. The main sites like the Lennon Wall, Prague Castle, Charles Bridge, and Old Town Square are a must see. Do yourself a favour though and try to get off the beaten path and check out places like the Kafka Museum, Rigierovy sady park, and St. Vitus Cathedral.

This is a capital like no other. It's mainly known as the home of the Hungarian Parliament Building, the Sziget Festival, and the Széchenyi Baths. Make sure you carve out time to see sights on both sides of the river like Heroes Square, Vajdahunyad Castle, Chain Bridge, Fisherman's Bastion, Shoes on the Danube, and Buda Castle.

The Art Nouveau style of the Latvian capital of Riga is a refreshing change from the skyscrapers that usually accompany capital cities. This city can be reached by bus, plane, or ferry and boasts city center attractions like Riga Castle, Three Brothers, House of the Blackheads, Swedish Gate, St. Peter's Church, and Riga Market.
